Application & Software Testing Services: An Outlook

Each amendment to a piece of software, each new piece of functionality, each attempt to fix a defect, introduces a possibility of an error. For each error, the risk of the software not meeting its target increases. Strong software testing services aims at reducing this risk.

We use quality assurance processes to prevent bugs from entering the software, but the only thing we can do to reduce the number of errors is by testing the software. Following the life-cycle of software testing services, the bugs/errors can be identified and resolved.

Software testing services allows us to quantify the risk in a piece of software warned. After the changes are made, the software can be run in a controlled environment to observe its behavior. This guides the decision to move to the next phase of the project or yet try to correct the issues.

In some cases, software testing services may be effectively used to guide software development. Following the statistical models and methods for software testing services like usability testing, software development can move to defocus a structured discipline.

Application Testing Services in the Software Development Life Cycle

Software testing services primarily aims at minimizing the software risks. Uncertainties related to the software development and design factors can derail and minor risks can delay the project. Using a software development test cycle, you can identify the degree of risk, make well-versed decisions, ultimately decrease uncertainty and remove errors.

Software testing services is the only way in the arsenal of development that reduces defects. Planning, design and quality assurance reduces the number of defects in a product, but cannot eliminate those that are already there. Any type of coding change introduces more errors because it shifts the perfect state to an unknown state.

Ideally, the tests should be conducted throughout the development life cycle. In most cases (as in the waterfall model) it is simply added to the back end. The purpose of software testing services is to reduce the risk, than if the risk accumulates over the project to be solved at the end – in itself is a risky tactic.

This could be taken as a viable approach. Allowing developers to concentrate on building software components and then moving to fix bugs, helps them segregate work and focus on one type of task at a time.

But, the complexity of solving the issues rises as soon as there is an increased gap between development and resolution. In any software development project large enough, this shift is too long. It is better to distribute the various software testing services phases throughout the lifecycle to detect errors as soon as possible.

Traceability

Another feature of software testing services is confirming the deliverables. Given a fairly complex project with hundreds or maybe thousands of gaming licensee claims, how would you know that you have deployed all of them? How do you demonstrate at the testing or launch that a specific requirement is met? How do you track the delivery status on specific requirements for development?

This problem is related to traceability. On a small project, building a table of elements of design and item of code helps you map the requirements and implement it correctly. However, on a large project, high number of requests overwhelm the type of traceability. It is also possible that one requirement may be filled with several design elements, or a single element in the design satisfies several requirements. This makes tracking the reference numbers difficult.

If you need a better solution, I propose off-the-shelf system tools available to track the requirements. These tools integrate and link to identical software test tools to provide traceability. Such a system can automatically produce reports highlighting requirements undelivered or untested.

Software Testing Services Outlook

“A professional tester approaches a product with the attitude that the product is already broken – it has defects and it is their job to discover them. They assume the product or system is inherently flawed and it is their job to ‘illuminate’ the flaws. This approach is necessary in testing.”

Designers and developers approach the software with confidence that the changes they make are the right solution for a specific problem. But they are only assumptions.

Unless proved correct, they are mere predictions. Developers often overlook the fundamental ambiguities in the requirements for implementing the project, or fail to recognize them when they see them. These ambiguities are then a part of the code and represent a failure for the end-user needs.

The tester then takes a skeptical approach to offer a balance. The tester, not taking any face value, asks questions like “What?”, “Why”, “When” and “How”. They try to illuminate the darkest part of the project on the basis of investigation.

If testers can adopt this perspective for a certain part of the project, they can offer a crucial assessment for a balanced project. The first step towards a successful test approach is to recognize the need for this perspective.

Very nice post. I agree with you that It is better to distribute the various software testing services phases throughout the lifecycle to detect errors as soon as possible. Thank you for sharing this interesting and informative post on software testing.
